I was asked to make a 'nice' pencil holder. I provide the openscad file so you can set how many pencils you want it to hold. The customizer now allows you to change the slope of the pencils and you can preview the stand with the pencils in it as well.
The stl is for a 48 pencil holder (it's almost 200 mm in diameter). If you change the 'number_pencils' variable in openscad then you can set the number of pencils to hold and the diameter of the holder adjusts accordingly.
You can preview the stand with the pencils in it as well. Make sure the pencils don't try to occupy the same space!
